Answer:
C.) Y= 5/8x + 1 1/2
Step-by-step explanation:
To write the equation of a line, calculate the slope between points (4,4) and (-4,-1). After, substitute the slope and a point into the point slope form.
Substitute m = 5/8 and the point (4,4) into the point slope form.
Answer:
The average inventory depends on the manufacturing batch size.
Its formula is:
Step-by-step explanation:
The question is incomplete.
Question complete:
<em>"A machine makes two components, call them type A and B. It takes 250 seconds to switch production between the component types. During that time no production occurs. When in production, each unit of A or B requires 0.5 seconds to be completed. The two components, A and B are combined in an assembly process to make a final product, call it C. The assembly step can combine the two components into 1 unit every 2 seconds. What is the average inventory of B components?"</em>
We have two steps in this process: the manufacturing of A and B and the assembly process.
We are not told about the batch size, so we will treat that as a variable called n. This represents the amount of units (of A or B) that are manufactured per cycle.
Time (seconds) to manufacture n units of A and n units of B:
Time (seconds)to assemble n units of C
Then the total time of the cycle is:
The average inventory of B is n units per cycle, which lasts (3n+250) seconds.
For a batch size of 100 units, the average inventory is:
For a batch size of 1,000 units, the average inventory is:
